APPLICATION USAGE
       This  utility  is  typically  used in shell scripts, as shown in the EXAMPLES section. The
       special built-in utility : is sometimes more efficient than true.

EXAMPLES
       This command is executed forever:

	      while true
	      do
		  command
	      done

RATIONALE
       The true utility has been retained in this volume of IEEE Std 1003.1-2001, even though the
       shell  special  built-in  : provides similar functionality, because true is widely used in
       historical scripts and is less cryptic to novice script readers.

FUTURE DIRECTIONS
       None.
